My SX200TXRX has an oxygen sensor. My question is now with the E10 Fuel we must use in the NE, how is this affecting my fuel economy? Does Yamaha have an ECU map update to accomodate this if it does cause the engine to run more rich?
The one positive effect of using ethanol is that it increases octane. The great negative is that with increased usage of ethanol the price of feed corn has skyrocketed which has raised the price of milk, bead and other foods.
